This, invention is a combined clock and weighing scale, and one of the objects is to economize space and cost of production. Another object is to provide a combined.

8 clock and scale assembled in a neat, compact and attractive form and wherein certain parts and elements of the structure serve towards the functioning of both the clock and the scale. Other objects and advantages 1 will appear in the course ofthe specification.

In carrying out this invention, a frame is provided consisting of top and bottom plates 1 and 2, which are flanged at the front and back, as shown at 3, and have boltholes 4 pierced through said flanges near the ends thereof. Front and back plates 5 and 6, having bolt holes 7 aligned with the bolt holes 4. are then secured to the top and bot.- tom plates by means of bolts 8, which are threaded medially as well as at both ends; the plates being secured in spaced relation upon the rear ends of these bolts by means of nuts 9. The elements which enable the device to function as a scale are mounted within these plates in a manner now to bepointed out. The center of the bottom plate 2 is pressed upwardly as shown at 10, and a guide pin hole 11 is pierced therethrough, and in which the lower end of a guide pin 12 is securely fastened. A scale standard 13 is provided and the lower end thereof is nicely bored out to form an air chamber 14 ada ted to slidingly engage the pin 12, the sai pin being machined so as to form a. close sliding fit in the chamber 14, and so that the co-action of these two elements is in the nature of an air-check, the purpose of which will be later pointed out. Just above the air chamber14 an equalizer bar 15 is pivotally and horizontally mounted over the standard 13. This equalizer is provided with downwardly turned hooks 16 at the ends, is slotted centrally as shown at 17 and is pivoted to the standard 13 by passing the latter .izer 15 and parallel to the through said slot 17, and then assin a pivot (pin 18 transversely throu h the medial slotte portion of the equalizer 15 and through the standard 13. The pin 18 is journaled either in the equalizer or in the standard, so as to afiord the equalizer a free oscillating movement. Immediately above the point of mounting of the equalizer '15, the standard 13 is widened and formed with an offset shoulder 19 at one side, and is slotted medially as shown at 20 to form a spindle slot, the saids'lot being cut through the standard in a direction generally perpendicular to the plane of vibration of the equalin 18. For a distance above the slot 20, t e standard 13 assumes a cross-likestructure as shown at 21, being flanged longitudinally in four directions from its axis and so that a crosssection thereof resembles a Greek cross. The upper end of the standard 13 is rounded as shown at 22, and so adapted to engage the socket 23 of the weighing platform 24. A hole 25 is cut. through the center of the to plate 1, through which passes the upper end of the standard 13. A rack 26 is fastened to the shoulder 19 with the teeth thereof projccting int-he plane of the equalizer 15. At each side of the standard 13, upper central portions of the plates 5 and 6 are cut away on all sides except along the inner vertical sides 27, and these portions are then turned perpendicularly inward to f0. 11 hangers 28 etween which. are journaled guide sheaves 29 which embrace from opposite sides the two opposite flanges of the cross-like portion 21 of the standard 13, whereby this standard is held and guided to an easy reciprocating action, vertically. A spindle 30 is journaled between the plates 5 and Gadjacent the rack 26, and this spindle carries a rigidly r'nount- .ed pinion 31 in mesh with the rack 26, and

a rigidly mounted spur gear 32 at the rear end of the spindle 30. A scale hand spindle- 33 is journaled through the'plates 5 and 6 and is passed through ,the spindle slot 20. The forward end of this spindle carries the rigidly mounted scale hand 34, .while the rear end carries the rigidly mounted inion 35 which is flanged on the back su ace to serve as a guide for the gear 32, which is placed in mesh with the said pinion 35.

Acoiled equalizer spring 36 isprovided the lower end of which is hooked over an en of the equalizer 15, while the upper end is threaded and is extended throng a hole 37 side thereof from the pivotal in the top plate 5. An adjustment nut 38 is then turned down upon the said threaded end. A hanger rod 39 is hooked by its lower end over the opposite end of the equalizer 15, the upper end of the hanger being threaded and passed through a hole 40 in the plate 5. An adjustment nut 41 is likewise turned down upon this threaded end of the hanger. Thus the nuts 38 and 41 have bearings upon the plate 5, and by turning these nuts the equalizer 15 may be readily adjusted and the tension of the spring 36 regulated as ma be required. A scythe-shaped counter ba ance arm 42 is pivoted at one end by a pin 43 which is set into the inner face of the back plate 6 near one side thereof. The pin 43 is in approximate horizontal alignment with the &X1S of the pinion 35, and the free end 44 of the element 42 is curved upwardly past the pinion 35, and upon the opposite oint 43. The upwardly curved arm 44 of t e element 42 carries its concaved edge turned towards the periphe of the pinion 35, and a curved rack 45 is fhstened to this concaved ed e and placed in mesh with the pinion 35; the curve of the arm 44 and rack 45 relative to the pivotal point 43, conforming to thesegment of a circle drawn u on the point 43 as a center. The weight 0. the element 42 is constantly exerted in one direction against the pinion 35, which causes the lash of the gear to remain on one side and so prevents the scale hand 34 from shifting out of place after the scale. has been balanced. The air check afforded by the piston-like action of the pin 12 in the chamber 14 serves to cushion the downward movement of the scale platform 24, when the scale is in use. The trapped air, however, gradually flows out past the pin 12, and the scale elements described then function to record the full weight of the articles upon the platform 24. The elements described complete the scale mechanism, except the provision of a cali-v brated dial for the scale hand, but as this is combined with the dial for the clock hands, its provision will be described in connection with the clock mechanism.

The elements of the clock mechanism are assembled in front of the scale mechanism. A tubular minute hand spindle is mounted over the forward end of the scale hand spindle 33 and adapted for free rotation thereon, the outer end of the minute hand spindle falling short of the end of the scale hand spindle. The clock minute hand 51 is secured to ileouter end in the conventional manner and adapted to revolve immediately back of the scale hand. A timing gear wheel 52 is rigidly mounted upon the inner end. A spindle 53 is journaled through the plates 5 and 6 at the side of i and a little below the spindle 33. A pinion 54 is secured to the forward end of this spindle and placed in mesh with the gear 52. A milled button 55 is rigidly mounted upon the rearwardly extended end of this spindle. A short, tubular, hour hand spindle 56 is mounted over the outer or forward end of the s indle 50, and is adapted to 1'0 tate freely tliereupon. The forward end of the spindle 56 falls a little back of the end of the spindle 50, and the hour hand 57 is rigidly secured thereto, and is so adapted to revolve immediately back of the minute hand 51. A pinion 58 is rigidly mounted at the rear end of the spindle 56, which may be termed a clock mechanism connecting pinion. Additional frame plates 59 and 60 may be provided and fastened in place upon the bolts 8 by means of nuts 9, the plate 59 being positioned at the forward ends of the bolts, and the plate 60 medially, as shown, the spindles 33 and 50 being extended through both these plates, and the spindle 56 to the plate 59 only. Any conventional form of clock mechanism (not shown) may be mounted between the plates 59 and 60 and operatively connected to the pinion 58 and to the spindle 50, in usualmanner. By turning the button 55, the clock hands may be revolved and the clock set in the usual way. Any convenient forms of extension controls for the clock regulating trigger and the winding mechanism may be provided and extended out back through the frame plates. For instance, for an extended control for the regulator trigger (not shown) a spindle 61 may be journaled through the frame plates, and a fork 62 mounted at the inner end adapted to engage the said trigger (not shown), while a small lever 63 is mounted at the outer or back end. Similarly for an extended control for the winding mechanism, a rod 64 is extended through the frame plates, the inner end of the rod having a squared socket 65 for engaging the winding stem (not shown) of the clock, while the outer end of the rod is bent to form a handle 66.

The housing includes a base 70, top 71, sides 72, back 73, dial plate 74, which is marked with the hours of the day in usual form, and in addition carries upon its outer edge any common form of scale or weight calibrations, together with letters, characters and figures, as shown, to represent the weight of the article placed upon the scale platform, as the relatively long scale hand 34 travels around this set of characters. The usual door frame 75 is hinged to the main housing, and supports the glass 76, through which the clock and scale hands may be observed. The housing may be secured together in any desired or conventional manner, and is provided with apertures 77 through which are rojected the several extremities of the sea e and clock mechanisms described.
